Growing with AGGRAND

 

Wine Grapes

Wine grapes (vitis vinifera, vitis labrusca, vitis rotundifolia spp.) do best on rather poor, but fairly deep (2-3 feet), gravelly and well-drained soils with a south to south-east exposure. Proper nitrogen fertilization of grapes can generally be achieved with regular applications of compost worked into the top 2-3 inches of soil around the vines, 2-3 weeks before bud burst. Supplemental nitrogen should only be applied when annual vine growth is inadequate, or leaves are a lighter green.

 

Per-acre mix ratio:fresh grapes on the vine, waiting for harvesting and wine production

 

1st application: 2 gallons AGGRAND Natural Fertilizer, 1 gallon AGGRAND Natural Kelp and Sulfate of Potash and 100 gallons of water. Root zone irrigate in early spring.

 

2nd application: 1 gallon AGGRAND Natural Fertilizer, 0.5 gallons AGGRAND Natural Kelp and Sulfate of Potash and 50 gallons of water (leave AGGRAND Natural Kelp and Sulfate of Potash out if leaves are yellowing or vines lack vigor). Foliar feed in spring at pre-bloom stage (2-5 days prior to bloom).

 

3rd application: 0.5 gallons AGGRAND Natural Kelp and Sulfate of Potash and 20 gallons of water. Foliar feed at berry set.

 

4th application: 0.5 gallons AGGRAND Natural Kelp and Sulfate of Potash and 20 gallons of water. Foliar feed at beginning of ripening (veraison).

 

5th application: (Optional) Repeat first application in fall after harvest. Till into soil with organic matter or legume cover crop.

 

New planting: Use same rates given under 1st application, working into soil in planting zone, along with well-rotted manure or compost.

 

Rates vary according to soil fertility and other inputs used. Higher dilution rates are more effective than lower dilution rates. Two or three lighter applications may be more effective than one heavy application. If other constraints only allow one trip over the field, do not exceed a 3 percent dilution rate (3 gallons AGGRAND fertilizers to 97 gallons water).

 

To reduce susceptibility to attack of insects and disease-causing organisms, apply a per-acre mixture of 1 gallon AGGRAND Natural Fertilizer or 1 quart AGGRAND Natural Kelp and Sulfate of Potash and 35 gallons of water when signs of infestation become apparent.
